The fee cuts come a little more than a week after BlackRock CEO Laurence Fink said at a financial-services conference that his firm would lower the fees of its own iShares ETFs to better compete with Vanguard Group, whose ETFs have rapidly accumulated assets at the expense of some iShares products.

The fee cuts include a wide spectrum of ETFs, according to the filings. For example, the Schwab International Equity ETF will now charge an annual expense ratio of 0.09%. Previously, the fund charged 0.13%, according to its website.

The Schwab U.S. Large-Cap ETF, which previously charged 0.08%, will now charge 0.04%, according to the filing. By comparison, the Vanguard S&P 500 ETF currently charges 0.05%, and the iShares S&P 500 Index ETF charges 0.09%.

The Schwab U.S. Broad Market ETF, which previously charged 0.06%, will now also charge 0.04%.
